Probe traffic information formed at the probe center 13 is transmitted to each driver by means of communication, broadcasting, or the like through the relay base 11 by radio waves.

Next, the acquisition method of probe information is demonstrated using FIG. In FIG. 4, the case where a motor vehicle runs on the trunk road R1 and a driver makes a mobile phone call state is demonstrated as an example. In this Fig. 4, the vehicle consists of a portion passing through P0 which is a starting point.

In addition, in this FIG. 4, the mobile telephone base station 30, the mobile telephone base station 31, the mobile telephone base station 32, the mobile telephone base station 33, the mobile telephone base station in front of the starting point P0 along the trunk road R1. 34, a cellular phone base station 35 is provided. This mobile phone base station 30 has a communication area 30A, the mobile phone base station 31 has a communication area 30B, and the mobile phone base station 32 has a communication area 30C. The mobile phone base station 33 has a communication area 30D, the mobile phone base station 34 has a communication area 30E, and the mobile phone base station 35 has a communication area 30F. Each has it.

In addition, the trunk road R1 of FIG. 4 is divided into branch road r1, branch road r2, branch road r3, branch road r4, and trunk road R3 on the way. And this trunk road R2 runs in the same direction as trunk road R1.

In FIG. 4, the automobile assumes the case of traveling by the trunk road R1. Now, when the car which is running on the trunk road R1 passes through the starting point P0 of the trunk road R1, and enters the communication area 30A of the cellular phone base station 30, the driver of the vehicle is the point P1. On your phone. Then, the identification number of the cellular phone obtained from the cellular phone at the start of the cellular phone call, the calling time of the cellular phone, the cellular base station used for the call, the area and location information in the cellular base station, and the like are processed by the cellular phone company 10. It is grasped | ascertained by the apparatus (data processing apparatus of probe traffic information). Then, the cellular phone base station is grasped by the cellular phone base station 30 that has received the radio wave of the cellular phone sent by the driver of the automobile, and it is detected in which sector of the communication area 30A of the cellular phone base station 30. . In addition, from what strength of the radio wave of the cellular phone received by the cellular base station 30 is located in which sector of which sector of the communication area 30A of the cellular base station 30, this information is grasped as positional information. . This specification is performed by the processing apparatus (data processing apparatus of probe traffic information) of the cellular phone company 10.

The mobile telephone starts communication using the mobile telephone base station 30 as a base station, and the position detection of the mobile telephone is performed. It is assumed that this cellular phone does not disconnect and enters the communication area 35A of the cellular phone base station 35, continues to walk to the point of the point P5, and ends the call. In the meantime, the probe information based on the call of the mobile phone of the driver of the car is determined by the position of the next mobile phone base station for each handover of each mobile phone base station (mobile phone base station is switched to the adjacent mobile phone base station). Detection is performed by position detection of the mobile telephone. Thus, the position of the main position from the point P1 of the communication start 30A of the communication area 30A of the cellular phone base station 30 to the point P5 of the communication area 35A of the cellular phone base station 35 of the call termination. The passing time is detected, and the overall moving distance and the moving time are measured. The speed (per hour) of the vehicle is calculated from this travel distance and travel time. The calculated speed (per hour) of the vehicle is stored in the calculation processing database 26G of the data processing device 20 of the probe traffic information of the mobile phone company 10.

In the above, the case where the cellular phone holder is a driver of an automobile has been described. However, not everyone who rides a car is a driver, but may be a passenger seat in a car, a passenger in a taxi, or a passenger in a bus. However, even a mobile phone holder who rides on a car other than this driver, if a mobile phone call is made while riding in a car, it is used as probe information based on the mobile phone call, just as a driver of a car makes a mobile phone call. Will be. Therefore, as mobile phone holders, all who are talking on the mobile phone while riding in the car are the targets of the probe information based on the mobile phone call.

In this way, all mobile phone holders are stored as probe information based on calls of the mobile phone. For this reason, it cannot be specified from the mobile phone whether the mobile phone holder who is talking on the mobile phone is walking, stopped on the road, is riding a bicycle, or is riding in a car. Therefore, it judges by the information acquired during the telephone call of a mobile telephone. That is, first of all, the information in which the mobile phone holder's moving distance between the two points calculated from two position detection values in one or a plurality of mobile phone base stations is &quot; 0 &quot; Since the holder is calling at home or calling without moving, it is excluded from the probe information based on the call of the cellular phone. In addition, the moving distance of the mobile phone holder between two points calculated from two position detection values in one or a plurality of mobile phone base stations with respect to the mobile phone in a call is not "0", but it is very slow. The travel distance of the holder, the travel time of the mobile phone holder calculated from the call initiation time and the call end time in the plurality of cellular base stations for the cellular phone in the call, and the travel speed of the mobile phone holder calculated from this travel distance and the travel time. (Per hour) is calculated, and the value is stored and stored in the arithmetic processing database 26G of the data processing apparatus 20 of the probe traffic information of the cellular phone company 10. Significantly lower than this value for an automobile driving on the main road R1 is that the vehicle is parked on the roadside, the mobile phone holder is walking, or the bicycle is on the road. It judges that it exists, and excludes from probe information based on the telephone call of a mobile telephone. Specifically, the maximum speed may be 5 km. That is, when the movement speed calculated above is 5 km or less, it is determined that the vehicle is standing on the roadside and talking, or that the mobile phone holder is walking or traveling by bicycle, and the probe based on the mobile phone call It is excluded from the information.

In this way, the probe information is specified based on the call of the mobile phone moving in the automobile. These information are mobile phones based on the call of the mobile phone which moves the specific area X of the trunk road R1 for 10 minutes from 9:00 am to 9:10 am, for example, the month ○ month. Aggregate data on the holder's travel time. Then, the movement time data of the cellular phone holder based on the call of the cellular phone moving in the specific area X of the trunk road R1 is obtained. However, a mobile phone holder based on a call of a mobile phone moving in a specific area X of the main road R1 includes people moving by walking, people moving by bicycle, people moving by car, and the like. As described above, all of the data for which the movement time of the cellular phone holder does not correspond to the movement of the car moving in the specific area X of the main road R1 is ignored. And the data about the travel time of the cellular phone holder which moves the specific area X of the remaining trunk road R1 becomes a movement of a car. This data becomes data of the movement time of the cellular phone holder based on the call of the cellular phone moving the specific area X of the main road R1 by automobile.

The plurality of pieces of data of the mobile phone holder's movement time are usually concentrated in a specific movement time zone (for example, 25 to 30 minutes). From the value which concentrates on this specific moving time slot (for example, 25 minutes-30 minutes), it is determined that it is time required to move the specific area X of the current trunk road R1. The average value of the plurality of data of the movement time of this cellular phone holder is calculated, and this calculated average movement time is judged as the time required to move the specific area X of the current trunk road R1 by car. Based on the time required to move the specific area X of the trunk road R1 to the car, the moving speed is calculated from the moving distance, and the vehicle travels through the specific area X of the current trunk road R1 by car. Moving speed (speed) is calculated. This moving speed (h / h) is compared with a predetermined speed (for example, the legal speed stored in the road information database 26F, the normal average running speed of a car traveling in the area), and the moving speed (h) Is slightly slower than the predetermined speed (e.g., 25% slower than the predetermined speed), is determined to be "congestion", and the movement speed (hours) is significantly slower than the predetermined speed (e.g., , When the speed is greater than 25% and the speed is 50% slower than the predetermined speed), it is determined as "congestion", and otherwise, it is determined as "good". This congestion information and congestion information are provided to the driver. Examples of this method include a method of directly transmitting to a driver, a method assigned by a management company, and the like.

Although not shown, probe information based on a call of a mobile phone moving in many of these automobiles is stored and stored in an external storage device connected to the data processing device 20 of probe traffic information of the mobile phone company 10. . The information stored and stored in the external storage device connected to the data processing device 20 of the probe traffic information of the cellular phone company 10 collects for one year, and based on these information, monthly, weekly, It is used as probe traffic information (congestion information, congestion information) on the roads of the whole country about daily and time zones.

Next, a case in which a car runs on the main road R1 will be described taking as an example a state in which a driver makes a non-call on a mobile phone. Here, the vehicle starts from the portion passing through the starting point P0.

In Fig. 4, with respect to the automobile, when the automobile passes through the starting point P0 of the main road R1 and enters the communication area 30A of the cellular telephone base station 30, the cellular phone is its nearest cellular telephone base station. In step 30, a position registration request is made. Now, the mobile phone base station detects the position of the mobile phone at the point P1, and then registers the position of the mobile phone at the cell phone base station 31 at the point P2. Position detection is performed between two points P1 and two points P2, and the distance therebetween is calculated from the map data. Then, the identification number of the cellular phone obtained from the cellular phone at the time of the location registration request of the cellular phone, the cellular phone base station that received the location registration request, the area and location information in the cellular phone base station, and the like (processing device of the mobile phone company 10) Data processing device for traffic information). The cellular phone base station detects whether the cellular phone held by the driver of the automobile is the cellular phone base station 30 that has made a location registration request, and in which sector of the communication area 30A of the cellular phone base station 30 is located. do. Further, from the strength of the radio wave at the time of request for registration of the location of the cellular phone received by the cellular phone base station 30, it is identified which region of which sector of the communication area 30A of the cellular phone base station 30 is located. It is grasped as positional information. This specification is performed by the processing apparatus (data processing apparatus of probe traffic information) of the cellular phone company 10.

At the same time, the time from the time of the position registration request of the point P1 to the time of the position registration request of the next position registration request point P2 is measured. From this distance and time, the traveling speed is calculated. At this time, when the vehicle passes from the starting point P0 of the main road R1 to the point P2 and then moves to the point Z0 or to the point S0, the vehicle is out of the communication area of the cellular phone base station. Probe traffic information cannot be used.

In this way, the position registration request of the communication area 31A of the cellular phone base station 31 which is the point of the next position registration request from the point P0 of the position registration request start in the communication area 30A of the cellular phone base station 30. The position and the travel time to the point P2 are detected, and the overall travel distance and the travel time are measured. The speed (per hour) of the vehicle is calculated from this travel distance and travel time. The calculated speed (per hour) of the vehicle is stored in the calculation processing database 26G of the data processing device 20 of the probe traffic information of the mobile phone company 10.

In the above, the case where the cellular phone holder is a driver of an automobile has been described. However, not everyone who rides a car is a driver, but may be a passenger seat in a car, a passenger in a taxi, or a passenger in a bus. However, even if the mobile phone holder who rides on a car other than this driver, if the position detection is performed while riding in the car, the probe based on the location registration request of the mobile phone is similarly to the position detection of the mobile phone held by the driver of the car. It is used as information. Therefore, as mobile phone holders, everyone who is polling while riding in an automobile becomes an object of probe information based on a call of the mobile phone.

In this way, all of the mobile phone holders are stored as probe information based on the location registration request of the mobile phone. For this reason, it cannot be specified from the mobile phone whether the mobile phone holder whose mobile phone has requested a location registration is walking, stopped on the road, riding a bicycle, or riding a car. Therefore, it is judged as the information obtained during a telephone call. That is, with respect to the mobile phone which detected the position, the information whose mobile distance of the mobile telephone holder is "0" between two points computed from two position detection values in one or several mobile telephone base stations is going out. Since the position detection is performed for the mobile telephone of the mobile telephone holder who does not move or the mobile telephone held by a person who does not move, the mobile telephone holder is excluded from the probe information based on the position detection for the mobile telephone. In addition, by the position detection with respect to a mobile telephone, the movement distance of the mobile telephone holder between two points calculated from two position detection values in one or a plurality of mobile telephone base stations is not "0", but it is very slow. , The travel distance of the mobile phone holder, the travel time of the mobile phone holder calculated from the position detection time in the plurality of mobile phone base stations with respect to the detected mobile phone, and the travel speed of the mobile phone holder calculated from the travel distance and the travel time. (Per hour) is calculated, and the value is stored and stored in the arithmetic processing database 26G of the data processing apparatus 20 of the probe traffic information of the cellular phone company 10. This value is remarkably low from the minimum speed (per hour) in the case of a car traveling on the main road R1, where the vehicle is parked at the roadside, the mobile phone holder is walking, or the bicycle is being detected. It determines that it is, and excludes it from probe information based on the position detection of a mobile telephone. Specifically, the maximum speed may be 5 km. That is, when the movement speed calculated above is 5 km or less, it is determined that the vehicle is standing on the roadside and making a call, or that the mobile phone holder is walking or traveling by bicycle, and the probe information based on the mobile phone call. Is excluded from.

When the automobile moves from the point P2 to the point P3, the cellular phone owned by the driver of the automobile enters the communication area 32A of the cellular phone base station 32. Then, by moving from this point P2 to the point P3, the traveling speed from the point P2 to the point P3 is similarly calculated from the distance and time. Here, when the vehicle travels on the main road R1 and designates a point S2 or a point S3 within the communication area 33A of the cellular phone base station 33, the vehicle is moved from the probe traffic information. The time required to travel from point P3 to point S2, point S3 is provided. However, when the automobile designates the point P4 of the branch road r4, it becomes a handover and the provision of the time required to travel to the point P4 is not performed. Then, the automobile travels on the branch line road r4, enters into the communication area 34A of the cellular phone base station 34, returns to the trunk road R1 again, and then communicates with the communication area 35A of the cellular phone base station 35. Enter Then, probe traffic information is acquired again by position detection.

In this way, the probe information is specified based on the position detection with respect to the cellular phone moving in the automobile. These information are based on the position detection for the mobile telephone which moves the specific area X of the trunk road R1 for 10 minutes from 9:00 am to 9:10 am on the ○ month ○, for example. Aggregate data of mobile phone holder's travel time. Then, the movement time data of the cellular phone holder based on the position detection with respect to the cellular phone moving in the specific area X of the trunk road R1 is obtained. However, the mobile phone holder based on the position detection for the mobile phone moving in the specific area X of the main road R1 includes a person who moves by walking, a person who moves by bicycle, a person who moves by car, and the like. As described above, all of the data for which the mobile phone holder's movement time does not correspond to the movement of the car moving in the specific area X of the main road R1 is ignored. And the data about the travel time of the mobile phone holder which moves the specific area X of the remaining trunk road R1 becomes a movement of a car. This data is the data of the movement time of the cellular phone holder based on the position detection with respect to the cellular phone which moves the specific area X of the trunk road R1 by automobile.

The plurality of pieces of data of the mobile phone holder's movement time are usually concentrated in a specific movement time zone (for example, 25 to 30 minutes). From the value which concentrates on this specific movement time slot (for example, 25 minutes-30 minutes), it is determined by the time required to move the specific area X of the current trunk road R1. The average value of the plurality of data of the movement time of this cellular phone holder is calculated, and this calculated average movement time is judged as the time required to move the specific area X of the current trunk road R1 by car. Based on the time required to move the specific area X of the trunk road R1 to the car, the moving speed is calculated from the moving distance, and the specific area X of the current trunk road R1 is driven to the car. The moving speed (speed) that travels and moves is calculated. This moving speed (h / h) is compared with a predetermined speed (for example, the legal speed stored in the road information database 26F, the normal average running speed of a car traveling in the area), and the moving speed (h) Is slightly slower than the predetermined speed (e.g., 25% slower than the predetermined speed), is determined to be "congestion", and the movement speed (hours) is significantly slower than the predetermined speed (e.g., , In the case of a speed exceeding 25% of the predetermined speed and 50% slower) is determined as "congestion". This congestion information and congestion information are provided to the driver. Examples of this method include a method of directly transmitting to a driver, a method assigned by a management company, and the like.
